𝗖𝗼𝗺𝗲𝘁 𝗿𝘂𝗻𝘀 𝗰𝗶𝗿𝗰𝗹𝗲𝘀 𝗮𝗿𝗼𝘂𝗻𝗱 𝗝𝘂𝗽𝘆𝘁𝗲𝗿 Friends, I watched an AI agent complete my students' coding exercises in real-time, and I'm shook 🤯 I tested Perplexity's Comet browser on a Jupyter notebook with eigenvalue problems I assigned to my class… (video at the bottom of this thread)

I am happy to share that I have been awarded a Dutch Research Council (NWO) Veni personal grant! www.nwo.nl/en/news/200-...

nwo.nl200 researchers receive Veni grants | NWOIdentifying when children are most at risk of being taken into care within youth protection programmes. Improving the quality of surgery with video analysis. The interaction between wind and vegetation for optimising the resilience of coastal dunes. Developing reliable algorithms for statistical learning with interactive decision science. These are four of the two hundred research projects by researchers who have been awarded a Veni grant. Each researcher will receive a maximum of 320,000 euros. The grant is an incentive for adventurous, talented and groundbreaking researchers to further develop their own research ideas over the next three years.

FastFlows focuses on accelerating scale-resolving turbulent flow simulations combining #CFD, #HPC, and #ML. This enables the integration of such simulations into rapid industrial design cycles, providing accurate and physical solutions with reduced turnaround time.

Makie v0.24 is out! One of the biggest architectural updates yet—bringing better performance, cleaner internals, and new plotting capabilities. A big step toward Makie 1.0. makie.org/website/blog... #JuliaLang #OpenSource #Visualization #Plotting #HPC #MakiePlots #WGLMakie #Makie

makie.orgmakie.orgMakie v0.24 focuses on a comprehensive overhaul of our internal architecture, specifically replacing Observables in our backend code with a more robust system. This fundamental change touches nearly every component of the codebase, making it one of our most ambitious refactoring efforts to date.

v1.4.0 includes a new set of performance improvements and features such as - Explicit LES subgrid-scale models - Custom user-defined function that is called during every time step - Easy to run an co-visualize with the new routine, viz! - Custom dynamic boundary conditions and body forces 2/2

Our latest preprint on "Mesh-free sparse identification of nonlinear dynamics" is out! In collaboration with Mars Gao and Nathan Kutz, we explore a novel SINDy framework to uncover dynamical systems from scarce, noisy, and non-uniformly sampled data. 🔗 arxiv.org/abs/2505.16058 #SINDy #PDE #SciML #ML

Leveraging neural networks and automatic differentiation, mesh-free SINDy demonstrates robust PDE discovery and computational efficiency for a variety of 1D and 2D systems.

#Overleaf is down and some are freaking out about a deadline coming right up... The standard work-local & push-to-remote approach is clearly not as widespread as I thought!

using an explicit LES model and a central difference scheme for the convective flux, we match nicely experimental results from the 70s! (doi.org/10.1017/S002...) Results with N=64^3 cells and Smagorinsky-Lilly turbulence model

I've often struggled to explain _why_, even as a novice, I enjoy #julialang so much, often falling back to "It just feels nice." Apparently, I should have just let the Julia developers explain it. Came across the following from "Why We Created Julia" from 2012-02 and it all makes more sense now.

Font et al. show a deep reinforcement learning-driven controller that cuts turbulent separation bubbles more effectively than periodic forcing. Trained on a coarser grid, it transfers smoothly to fine-grid simulations. www.nature.com/articles/s41...
